16. P. Dept. – 1 RAW MATERIAL HANDLING PLANT (RMHP)
1. OVERVIEW
Visakhapatnam Steel Plant is one of the most modern steel plant not only in the country but
also in the world. This has latest raw materials stacking and blending system. RMHP has the concept of
peripheral unloading which considerably reduces delay in taking over and handing over of rakes bringing
raw materials to the plant, there by increasing the availability of wagons. The Raw Material Handling
Plant is handling more than 24 million tons of various raw materials for 6.3 MTA
Raw Material Handling plant is meant for transporting materials from Raw Material yard /
Base mix yard to various units of the plant. The Major Raw materials required for Iron and Steel making
are Iron ore lump, Iron Ore fines, Sized iron ore, Flux limestone / dolomite, manganese, Quartzite coking
coal ( for Boiler operation & For Pulverized coal injection ) and coke. Lump iron ores, iron ore fines and
flux such as limestone and dolomite received by railway rake are unloaded in wagon tippler and stored
yard with the help of various stockyard machines.
Fig. 1.1 Overview of RMHP
Iron ore lump, flux such as limestone and dolomite, Coke is reclaimed by suitable stock
yard machine and are crushed in Ore crushing plant, Flux crushing plant and coke crushing plant
respectively to produce the size required. The above material is proportionately stacked by suitable
stacking machine in base mix yard and blended while reclaiming by blender reclaimer. The prepared base
mix is then transported to Sinter plant for sinter production. For feeding material to new Blast Furnace,
sized ore and flux are reclaimed by stock yard machine from respective yard and are transported by
17. conveyor. Sinter produced in sinter plant and coke from existing/new coke ovens is transported directly
to BF-3 stock house by conveyor. Purchased coke and necessary calcined lime from stock yard and new
lime calcining plant respectively are transported to SMS by conveyor. The waste product from the plant
is mainly dust and method of their disposal is through dust suppression system and inter plant
transportation.
1.1 The Raw Material Handling Plant in any organization is needed :
a) To have adequate storage capacity to store various raw materials depending up on the capacity of the
beds in the stock yard.
b) To blend raw materials, if needed, received from various sources, in order to supply homogeneous raw
materials.
c) To ensure methodical stacking and reclaiming of raw materials without mixing up of different raw
materials.
d) To process the raw materials and bring down the size to the size as required by the customer
departments to improve their productivity and product quality.
18. P. Dept. – 2 COKE OVEN & COAL CHEMICAL PLANT
2. OVERVIEW
Coal is converted into coke by heating the prepared coal blend charge in the coke ovens in the
absence of air at a temperature of 1000o
C-1050o
C for a period of 16/19 hours. The volatile matter of coal
liberated during carbonization is collected in gas collecting mains in the form of raw coke oven gas passing
through stand pipes and direct contact cooling with ammonia liquor spray. The gas cooled from 800o
C to
80o
C is drawn to Coal Chemical Plant by Exhauster. The residual coke is pushed out of the oven by pusher
car through a guide into coke bucket. The red-hot coke is taken to coke dry cooling plant for cooling. The
main by-product in the process of coke making is crude coke oven gas and this has a lot of valuable
chemicals. Coal Chemical Plant recovers Ammonia (NH3), Tar and Benzol from CO-Gas. The primary
by-products from Crude CO Gas are Ammonium Sulphate (NH4)2SO4, Crude Tar, Crude Benzol and
cleaned coke oven gas. The cooled coke from CDCP (Coke Dry Cooling Plant) is separated into 3
fractions, BF Coke i.e. +25-70 mm, which is sent to Blast Furnaces, Coke Breeze i.e. +0-15 mm, which is
sent to Sinter making and nut coke i.e., +15-25 mm, which is also used in the Blast Furnaces.

21. P. Dept. – 3 SINTER PLANT
3. OVERVIEW
Sintering is an agglomeration process of fine mineral particles into a porous mass by incipient
fusion caused by heat produced by combustion within the mass itself. Iron ore fines, coke breeze,
limestone and dolomite along with recycled metallurgical wastes are converted into agglomerated mass at
the Sinter Plant, which forms 70-80% of iron bearing charge in the Blast Furnace. The vertical speed of
sintering depends on the suction that is created under the grate. At VSP, two exhausters are provided for
each machine to create a suction of 1500-1600 mm water column under the grate.
Fig. 3.1 Overview of Sinter Plant
SINTER PLANT – 3
For meeting the requirement of new Blast Furnace-3 to produce 2.5 Mtpa Hot metal, One
number of Sinter machine of 400 sq.m is envisaged. The Raw materials required to produce Product sinter
are Base mix consisting of 100% iron bearing material including revert material including revert materials,
flux, coke, floating return fines and calcined lime which is fed into Blast Furnace-3. Considering 80%
sinter ratio in the burden of new Blast Furnace, the requirement of Sinter charge will be 3.25 Mtpa for
production of 2.5 Mtpa Hot metal.
Hence, new sinter will receive Base mix which will be prepared in bedding and blending yard
by mixing all iron bearing materials and about 80% of flux and fuel. Balance flux and fuel, as well as
22. calcined lime, will be added in proportioning section of Sinter plant. The facilities envisaged are

24. P. Dept. - 4 BLAST FURNACE
4. OVERVIEW
Iron is produced in the Blast Furnace by smelting iron bearing materials with the help of coke
and air. The solid charge materials like sinter, sized iron ore, coke etc. are charged in the vertical shaft of
the Blast Furnace from top and hot air blast is blown through tuyeres located at the bottom. The oxygen
present in hot air combines with the carbon of coke and generates heat and carbon monoxide (reducing
agent). The reducing gases, while ascending upwards comes into contact with the descending charge
materials. Eventually the charge gets reduced and hot metal, slag and BF gas are produced. Hot metal and
slag is tapped from tap hole. The Blast Furnace gas which comes out from top of the furnace is cleaned
and used as fuel in the plant.

To achieve the desired hot metal production of 6.5 Mtpa, additional one number of BF is installed
with a capacity of 3800 Cu.M producing 2.5 Mtpa . The Raw materials required for manufacturing process
are Sinter, Sized ore, Quartizite, Coke and Injection coal. Raw materials and coke from stock yard are
transported to the stock house bunkers through junction houses. The main charging conveyor feeds the
burden into the Blast Furnace. Hot stoves deliver the hot blast into the Blast Furnace via bustle main and
tuyeres. Pulverized coal from coal grinding plant to coal distributor which distributes the coal into
individual tuyeres.
Inside Blast Furnace, the iron ore is reduced to form iron and slag, which collects at the hearth.
From there, Hot metal and slag is periodically tapped through tap holes. Hot metal is channeled via tilting
runners into torpedo ladle cars, which carries it away. Slag is granulated in the slag granulation plant,
dewatered and subsequently carried away by a conveyor to slag storage yard. The Blast Furnace top gases

27. P. Dept. - 5 STEEL MELT SHOP & CONTINUOUS CASTING
5. OVERVIEW
Steel is made in steel melting shop in the refractory lined vessels called LD Converters by
blowing oxygen through the hot metal bath. While iron making is a reduction process, steel making is an
oxidation process. The oxygen reacts with impurities like carbon, silicon, phosphorous, Sulphur, etc.
present in hot metal to produce steel. No external fuel is required as the silicon & carbon releases huge
amount of heat energy. Also the carbon reaction releases large quantities of gas rich in carbon monoxide
along with huge amount of dust. The gases released from the converter are collected, cooled, cleaned
and recovered for use as fuel in the steel plant. The entire molten steel at VSP is continuously cast at the
radial type continuous casting machines resulting in significant energy conservation and better quality
steel. 100% Continuous casting on such a large scale has been conceived for the first time in India.
Fig. 5.1 Overview of Steel Melt Shop & Continuous Casting
STEEL MELT SHOP – 2

of Hot Metal. The Raw materials required for manufacturing process are - Hot Metal, Scrap, Flux, Ferro
alloys. New Steel melt shop comprises of two converters each of 150 cu.m capacity. Two Numbers of
Laddle Furnaces were envisaged to make the operation of the two converters independent of the
requirements of continuous casting machines thereby acting as buffer between the converter and the caster.
The steel temperature and steel chemistry will be homogenized in LF by inert gases and One
number of RH degassing system is envisaged for production of special grade with low gas content. There
are three numbers of six strand billet mill. Three casters are available for 200 days in a year and two casters
are available for 165 days in a year. Cast Billets will be fed to new Special Bar Mill and Wire Rod Mill.

peripheral unloading which considerably reduces delay in taking over and handing over of rakes
bringing raw materials to the plant, there by increasing the availability of wagons.
The Raw Material Handling Plant is handling more than 24 million tons of various raw
materials for 6.3 MTA.
Raw Material Handling plant is meant for transporting materials from Raw Material yard /
Base mix yard to various units of the plant. The Major Raw materials required for Iron and Steel making
are Iron ore lump, Iron Ore fines, Sized iron ore, Flux limestone / dolomite, manganese, Quartzite
coking coal ( for Boiler operation & For Pulverized coal injection ) and coke. Lump iron ores, iron ore
fines and flux such as limestone and dolomite received by railway rake are unloaded in wagon tippler
and stored yard with the help of various stockyard machines.
Iron ore lump, flux such as limestone and dolomite, Coke is reclaimed by suitable stock yard
machine and are crushed in Ore crushing plant, Flux crushing plant and coke crushing plant respectively
to produce the size required. The above material is proportionately stacked by suitable stacking machine
in base mix yard and blended while reclaiming by blender reclaimer. The prepared base mix is then
transported to Sinter plant for sinter production. For feeding material to new Blast Furnace, sized ore and
flux are reclaimed by stock yard machine from respective yard and are transported by conveyor. Sinter
produced in sinter plant and coke from existing/new coke ovens is transported directly to BF-3 stock house
by conveyor. Purchased coke and necessary calcined lime from stock yard and new lime calcining plant
respectively are transported to SMS by conveyor. The waste product from the plant is mainly dust and
method of their disposal is through dust suppression system and inter plant transportation.

3. WAGON TIPPLER
3.1 DESCRIPTION OF WAGON TIPPLER ARRANGEMENT
The wagon tippler consists of gears and units, listed in the general drawing specification 01-PRH1-02-M-
0001.
The rotor is set on the roller supports where it rotates about the horizontal axle. It consists of three ring
disks. These disks on the sides are linked with the beams, and from the bottom side of the left and the
right beam they are connected with the stationary platforms. Due to this the rotor is rigid metal work.
For moving the open wagon into the rotor and stopping it in the required position the rail-road rails and
friction brake devices are installed on the platform.
Inside the rotor a mobile resting wall is set on the levers. The levers are arranged so, that make
parallelogram gears, providing the wall with the ability to fix the open wagons of different width, making
64. flat-parallel motion.
The wall in its turn consists of two parallel set beams hinge – connected.
The wall is moved by the hydraulic cylinders making the whole unit of the hydraulic drive. The eight
cylinders (four on each beam) bring the wall into motion. Each cylinder has a pilot controlled check
valve that locks the cylinder piston space after the open wagon fixing and shutting off the control valve.
On the rotor side beams two clamps are located on each side which fix the unloaded open wagon along
its upper binding.
The clamps consist of horizontal beams, whose support surfaces are lined with rubber plates to prevent
damages of the open wagons. Each beam is hinge connected with two pairs of levers that make the
parallelogram gears. The free ends of the levers are fixed in the hinge supports of the side beams.
Each clamp is moved with the help of two hydraulic cylinders, one side of which is fixed through a hinge
bearing on the side beam of the rotor, the other side is fixed as well, on the load-bearing levers. Each
cylinder has also a pilot controlled check valve, locking to the rod space of the cylinder after the open
wagon fixing and shutting off the control valve.
On the clamps (right), located on the side of the material unloading, are set the fields for the replacing
unloaded material onto the bin grate, apart from the rotor, during start age of unloading.
On the resting wall are located also three vibrators for the forced surface conditioning of the open wagons
from the material sticked to the walls and the floor.
The vibrator unit is an arm with a vibrating beam and the vibrator HB11-50 fixed on it. The arm is hinge
attached to the resting wall with an axle and is pressed to it with springs. During the fixation of the
vibrating beams are pressed out of it, staying pressed to the walls of the open wagon and this provides the
contact of the vibrating beam with the open wagon.
As the resting wall is put on the mobile levers, rested on the hinge bearings, it has undesirable level of
freedom (ability to move lengthwise). To fix it and to prevent from possible movements lengthwise,
between the disks and the face surfaces of the wall roller rests are set.
Two separate tilting drives (left and right) are basic gears of the wagon tippler. Each drive has one drive
gear wheel. The drives are not connected with a rigid shaft; its functioning made by the metal
construction of the rotor that provides necessary rigidity and strength even when one drive operates. The
drives are supplied with shoe brakes with electromagnets of the direct current, and with additional
mechanical fixation of the drive couplings, in case of necessary rotor stopping in an intermediate position
for clearing the open wagons manually.
The rotor rests on the roller supports through the circular rails (tyres). Each support has four rollers,
connected in pairs with balance beams, hinge rested on the general frame. The rollers of the one outer
support are made two – flanged, the others are unflanged. All of them are made of the high – strength
steel 65T and designed for a long term of operating without a change.
Together with the wagon tippler the electro – mechanical fixing arms in the starting position are also
delivered. They are located on the foundations between the rails of the approach ways on the both sides
of the wagon tippler.
The purpose of the fixing arms is a strict alignment of the rails of the approach ways of the platform rails,
and also protecting of the rotor from a casual turning during moving open wagon into it. The fixing arm
consists of the fixing rod with a roll moving in four rolls fixed on the general frame. The fixing rod is put
into motion with a screw ending drive the IIBM type.
Peripheral unloading system is the specialty of VSP
18 to 20 Wagons tippled per Hour.
The tippling process also depends on the availability of stacking streams (stackers, conveyors)
65. The Wagons are placed in the Tippler with the help of PUSHER CARS.
Each Wagon Tippler has two pre – tippling lines and one pusher car in each line which are operated
with power supplied from DSL / bus bars.
Each pusher car has six axles each having a motor of 37 KW capacity and aided with electro –
magnetic brakes.
3.2 OPERATIONAL DESCRIPTION
The wagon tippler operates in the following way :
1. Purposed for unloading open wagons are moved to the wagon tippler with a pusher and one by one
are placed on its platform. Putting the open wagon to a certain position on the platform is made by the
engine – driver assistant visually on the equal distances from the symmetry of the platform;
2. The engine drive of the wagon tipper, after getting the allowance instruction of the assistant, sends
the command to the gears for tipping over. At this moment automatically, in a certain order, unfixing
of the rotor takes, then the clamps lowering, the wall moving, and (after the hydraulic drive operate
finishing) the drives switching as well. The drives of the tippler provide a smooth starting and
smooth stopping of the motor in the rotor in the extreme positions. The wagon tippler construction
makes it possible to turn the rotor to the angle of 175°, to stop it if it is necessary in any intermediate
position.
3. After the rotor is stopped in the tippled over state the vibrators are switched on automatically. The
operating period of the vibrators can be regulated and changed in the interval of 0….10 sec.
4. After unloading of the open wagon the tipping over drive motors are switched to the reverse motion,
and all the gears moving are repeated in the reverse order (the motor returns to the starting position,
the clamps are lifted, the wall is removed, the rotor is stopped). And besides, the switching on of the
clamps takes place at the movement when the rotor turns to 90° as minimum, and the wall removing
is made after the full stop of the rotor.
5. After the rotor returns to the starting position the next open wagon is moved by the pusher and
simultaneously the open wagon pushes off an empty one.
6. In case of not full dump of the open wagon the tipping over procedure is related. And in case of
necessity the cleaning is made manually, and the wagon should be stopped over 90°, the drive is
braked the drive pulleys are stopped, and also the safety measurements for the personnel should be
observed.
